What is the ASTM A928 standard?
ASTM A928, formally known as the "Standard Specification for Electric-Welded Ferritic/Austrian (Duplex) Steel Pipe with Addition of Filler Metal," is a standard developed by the American Society for Testing and Materials (ASTM). It covers the manufacturing requirements for welded duplex stainless steel pipe for use in corrosive environments such as chemical, offshore, and oil and gas.
The ASTM A928 Grade 1 S32750 super duplex stainless steel welded pipe we offer is an electric fusion welded (EFW) pipe made from S32750 grade super duplex stainless steel. The "Grade 1" designation indicates that the pipe is duplex welded using filler metal in all weld passes and then fully radiographically inspected to ensure weld integrity. It is suitable for demanding applications in the offshore oil, power, and chemical processing industries.
ASTM A928 Grade 1 S32750 Duplex Stainless Steel Pipe Applications
Oil and Gas: S32750 duplex stainless steel pipe can be used for submarine pipelines and pipelines transporting high-sulfur media.
Chemical Industry: S32750 duplex stainless steel round pipe can be used as piping for reactors and heat exchangers in strong acid (such as sulfuric acid and hydrochloric acid) and strong alkaline environments.
Desalination: S32750 duplex stainless steel welded pipe can be used in high-pressure reverse osmosis (RO) systems and seawater cooling systems.

What is the difference between ASTM A790 and A928?
ASTM A790 specifies the elements and requirements for the manufacture of seamless and welded pipes, while ASTM A928 only covers electric fusion welded pipes. ASTM A790 requires that duplex and super duplex steel pipes be welded without the addition of any filler metal.
Product Testing
The tests that stainless steel pipes undergo before leaving the factory include chemical composition, mechanical properties, dimensional accuracy, surface quality, non-destructive testing and corrosion resistance to ensure that they meet standards and usage requirements.
